Let's Britain in Matthew dowd and Martha Raddatz for more. Three weeks and a day before the election. Our polls show a four-point lead for Hillary Clinton. No question, Donald Trump behind right now. He needs major shift to get back in the race. When you looked at the race a month or so ago, I said it was about a field goal. Today, we're in the final less than 22 days, it's as if he's behind by four or five runs in the ninth inning. It's a much different thing. Can he come back? It's possible. Lit take a big debate. Right now this race falls in about a six-point Hillary Clinton lead. Martha, you spent time with voters at a key state of Pennsylvania. One of the surprises I think you found is that that access Hollywood tape didn't turn out to these stroerts be a game-changer. What the voters said backed up our ABC poll. They may not ling what he said. May not think his apology was sincere. Many voters said this would not affect their decision, men and women. One man saying he wasn't surprised by tape. One female voter saying she thought it was funny. Another saying she's heard that talk before from men and women. There were voter who is were disturbed by the tape, but seemed to fall into the one-third in the poll who would not likely have voted for him any way. The opinthuz yachl for Donald Trump is down. Who he's lashing out at, the media. Clinton. But claiming the whole election is rigged. It's fundamentally not the undecided voters. What's Hillary Clinton's fundamentally it's change. And the tape is her enthusiasm level is up to what Donald Trump's supporters level is. That's a major change. It has caused a two-point lead to a 6-point lead. He's trying to rile up the base. They're both in the final 22 days focused on the base and not undecided voters. Thank you both. Final presidential debit is Wednesday on ABC. I'll be anchoring our live coverage starting at 9:00 P.M. Eastern.
